Market context
Viktorija Golubic and Alycia Parks are scheduled to meet in the first or second round of Roland Garros in late May 2026. The 0% implied probability on this contract reflects either extreme confidence in Parks or significant uncertainty about match completion, given the settlement window closes just hours after the scheduled 5:00 AM ET start time. The tight window—with resolution at 09:00 UTC on 3 June—means any delay beyond the scheduled date triggers a 50-50 split, a material risk factor in clay-court tennis where weather disruptions are common.
Historically, Golubic has competed at Roland Garros multiple times without advancing deep into the draw, whilst Parks, despite her youth and ranking trajectory, has shown volatility in major tournaments. Head-to-head records between lower-ranked players in early rounds offer limited predictive value; recent form, court preference, and injury status matter more. Parks has been building consistency on clay, though Golubic's experience on the surface and baseline solidity remain assets.
The critical catalyst is confirmation of both players' fitness and draw placement in the days before the tournament. Any withdrawal or late schedule adjustment would immediately affect settlement conditions. Traders should monitor official Roland Garros draw announcements and ATP/WTA injury reports through late May. The 0% reading suggests the market may be pricing Parks as heavily favoured or reflecting genuine doubt about match execution within the compressed settlement window rather than a genuine assessment of competitive probability.
Methodology
This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to Best Prediction Markets, which mirrors the Polymarket order book directly.
Resolution & payout
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
